Double glazing offers a lot of benefits to homeowners. And while it can represent a significant up-front investment, it will likely pay for itself many times over in the long run. There are plenty of solid benefits to double glazed windows including improving home security and reducing your power bills. However, they also come with a couple of downsides that might be worth considering before you invest.
What is Double Glazing?
Before we get to the benefits, let’s have a look at exactly what double glazing is. Double glazing consists of two glass panes combined to create a single closed unit. The two panes are separated by a spacer made of either metal or polymer. This spacer contains a drying agent (a desiccant) that removes any moisture from the gap. A 12mm gap between the two panes is said to be the minimum distance for optimal thermal efficiency.
The unit is then sealed and the gap is filled with inert gas, usually argon. The gas helps to prevent thermal transfer between the glass panes, increasing the insulating properties.
Double glazing is commonly used on windows or doors on residential and commercial buildings and offers a range of benefits.
Glass readily conducts heat, which means that the outside heat is easily transferred through single-glazed windows during the sweltering Australian summers.
Double glazed windows solve this problem by having a vacuumed air gap between the panes. Since air is a poor conductor of heat, this layer helps to minimise thermal transfer and keep the heat outside the home.
During the winter, double glazed windows will function in a similar way, stopping the cool air from getting in and the heat from escaping. Up to 40% of a home’s thermal energy can be lost through the glass surfaces including windows and doors. Compared to single glazing, double glazed sliding doors and windows can reduce your home’s heat gain or loss by up to 30%.
Additionally, double glazing can also reduce condensation on windows, due to the inside pane being closer to room temperature. This lessens the chance of water damage on window frames and reduces the risk of mould.
Reduces Power Bills
With double glazed windows, you won’t have to rely as heavily on your AC system to maintain a consistent temperature in your home. A cooler interior during the summer means your air conditioners won’t have to work as hard to lower the temperature. Conversely, the trapped heat during the winter means you won’t have to use your heaters as much.
Reducing your use of heating and cooling systems makes your home more energy efficient, lowering the cost of your power bills and reducing your overall power consumption. Overtime, the money that you save from double glazed windows will eventually pay for the installation costs.
It’s important to be aware of how your actions affect the environment. Being conscious of how much power you consume is an excellent way of doing your part in protecting the planet.
By reducing your reliance on heating and cooling systems, double-glazed windows can reduce carbon dioxide emissions to up to 680kgs per year.
Improves Home Security
Double glazed sliding doors and windows can also be used to improve your home’s security. Two panes of glass are much more difficult to break than a single pane, which can make it harder for burglars to access your home through broken windows or glass doors.
Whether you’re working from home, have rowdy neighbours or want to block out the traffic noise, soundproofing is vital.
Double-glazed doors and windows dampen the noise vibrations that travel through them. The large air space between the two glass panes can reduce outside noise to up to 50%, which is a 10-decibel drop.
Additionally, both the noise reducing and insulating properties of double glazed windows can help you sleep better. A comfortable temperature and quiet bedroom will make it easier for you to get some well-needed shut-eye.
Improving your home’s quality and livability might also increase your property’s value.
Double glazing can be a significant investment up front. Potential buyers are often put off by the high asking prices of glazing suppliers. However, it’s important to remember that double glazing will save you a lot of money in the long run and end up paying for themselves many times over.
In addition, there are suppliers out there that offer affordable glazing solutions. When you decide to have double glazed windows in your home, consider your options in terms of the quality of supplier and their prices.
Can Limit Window Functionality
Double glazing can limit design options for doors and windows. Because of the extra bulk and weight of double glazing, some window and door designs and opening functionality may not be possible. However, with careful planning and clever design, this can generally be overcome.
On the whole, the benefits of double glazing outweigh its downsides. Double glazing is a great way of improving the quality of your home while simultaneously doing your part in protecting the environment.
